摘要： A reception device which communicates with a transmission device, the reception device including: a reception unit which receives a signal in which a plurality of data signals are multiplexed, from the transmission device; and a data signal detection unit which determines whether detection of transmission data for each data signal from the reception signal received by the reception unit is successful. The reception unit further receives, from the transmission device, a retransmission data signal corresponding to at least one of data signals for which transmission data detection has failed among the plurality of multiplexed data signals. The data signal detection unit determines whether re-detection of the transmission data included in the data signal corresponding to the retransmission data signal among the plurality of multiplexed data signals and a data signal not corresponding to the at least one retransmission data signal, from the reception signal and the retransmission data signal, is successful.
